Guys!!i want to ask a few question before buying myself an R4..
1)Is DSVideo works/compatible with R4?
2)Is Licks Media Player(LMP) works/compatible with R4?
3)Is ComicBookDS works/compatible with R4?
Hope to see some reply from you guys.. I'm just new here..thanks

I own an R4 (original thankfully) and apart from suggesting a different cart (Acekards are pretty cheap and a heck of a lot better), I can say that both DSVideo and Comicbook DS work perfectly on the R4. I can't say anything about LMP because I never used it (Moonshell user).

It's impossible to say because each fake R4 has different homebrew compatibility. One of them might do DSVideo and LMP but not CBDS, another might do LMP but not the other two. Some of them will not run any of them.
